增加 seaborn 中的刻度标签字体大小

Question

我的 seaborn 图有一个大问题。出于某种原因，轴上的数字是用非常小的字体打印的，这使得它们不可读。我试着用

来缩放它们

with plt.rc_context(dict(sns.axes_style("whitegrid"),
                     **sns.plotting_context(font_scale=5))):
    b = sns.violinplot(y="Draughts", data=dr)

没有帮助，这只会使轴文本变大，但不会使沿轴的数字变大。

Answer 1

here 的答案使 seaborn 中的字体变大 ...

import pandas as pd, numpy as np, seaborn as sns
from matplotlib import pyplot as plt

# Generate data
df = pd.DataFrame({"Draughts": np.random.randn(100)})

# Plot using seaborn
sns.set(font_scale = 2)
b = sns.violinplot(y = "Draughts", data = df)
plt.show()

Answer 2

扩展已接受的答案，如果您只想重新调整刻度标签的字体大小而不按相同数量缩放其他标签，您可以试试这个：

import pandas as pd, numpy as np, seaborn as sns
from matplotlib import pyplot as plt

# Generate data
df = pd.DataFrame({"Draughts": np.random.randn(100)})

# Plot using seaborn
b = sns.violinplot(y = "Draughts", data = df)
b.set_yticklabels(b.get_yticks(), size = 15)

plt.show()

Answer 3

此答案将单独解决设置 x 或 y 刻度标签大小的问题。
sns.set(font_scale=2) 来自 p-robot 将设置 所有图形字体。
Kabir Ahuja 的答案有效，因为 y 标签位置被用作文本。
- 如果有 y 标签文本，该解决方案将不起作用。

给出以下情节

import matplotlib.pyplot as plt
import seaborn as sns

# data
tips = sns.load_dataset("tips")

# plot figure
plt.figure(figsize=(8, 6))
p = sns.violinplot(x="day", y="total_bill", data=tips)

# get label text
_, ylabels = plt.yticks()
_, xlabels = plt.xticks()
plt.show()

yl = list(ylabels)
print(yl)
>>>[Text(0, -10.0, ''),
Text(0, 0.0, ''),
Text(0, 10.0, ''),
Text(0, 20.0, ''),
Text(0, 30.0, ''),
Text(0, 40.0, ''),
Text(0, 50.0, ''),
Text(0, 60.0, ''),
Text(0, 70.0, '')]

# see that there are no text labels
print(yl[0].get_text())
>>> ''

# see that there are text labels on the x-axis
print(list(xlabels))
>>> [Text(0, 0, 'Thur'), Text(1, 0, 'Fri'), Text(2, 0, 'Sat'), Text(3, 0, 'Sun')]

# the answer from Kabir Ahuja works because of this
print(p.get_yticks())
>>> array([-10.,   0.,  10.,  20.,  30.,  40.,  50.,  60.,  70.])

# in this case, the following won't work because the text is ''
# this is what to do if the there are text labels
p.set_yticklabels(ylabels, size=15)

# set the x-axis ticklabel size
p.set_xticklabels(xlabels, size=5)

没有 ytick 标签，因为
- y_text = [x.get_text() for x in ylabels] = ['', '', '', '', '', '', '', '', '']

设置yticklabel大小

# use
p.set_yticklabels(p.get_yticks(), size=15)

# or
_, ylabels = plt.yticks()
p.set_yticklabels(ylabels, size=15)

设置 xticklable 大小

# use
p.set_xticklabels(p.get_xticks(), size=15)

# or
_, xlabels = plt.xticks()
p.set_xticklabels(xlabels, size=15)

根据给定的情节

# set the y-labels with
p.set_yticklabels(p.get_yticks(), size=5)

# set the x-labels with
_, xlabels = plt.xticks()
p.set_xticklabels(xlabels, size=5)
